Abstract

A Riemannian manifold endowed with a conformal metric is proposed as a geometric model for the cortical magnification that characterises foveal systems. The eccentricity scaling of receptive fields, the relative size of the foveola, as well as the fraction of receptive fields involved in foveal vision can all be deduced from it.
